Hello Sir,
I'm travelling to India from USA via Etihad/AA as yourself. I have a 1:30 mins transit at Manchester. Can you please let me know whether I need a transit visa? I had a EAD/AP and also approved I-797, but I don't have a visa stamped on my Passport.
Your prior experience would be very valuable to me and I appreciate your time.

Thank you, Joe
